I'd like to know what locations throughout Asia inspired the design of Final Fantasy X.

I know a lot of South East Asia inspired the design, but more specifically, I am visiting Japan, China & Hong Kong in a couple of months, and would like to know what places they visited in these countries, so that I can go see them myself too.

Anything in relation to the Final Fantasy series, and even Tomb Raider series, I would love some pointers! Can't wait to visit these countries.
